r.7..G-Z control introduces systemic insecticides into the tree's vascular system and is effective over a longer period of time than foliar spraying. This bid item was not in the original bid package. (3) The third recommended change to the contract will be to add a bid item for the trunk injection of pesticides at a unit price based on the size of the tree - $6 per eight-inches of tree trunk circumference. This pesticide application introduces systemic insecticides into the tree's vascular system through the trunk with minimal damage. Trunk injection provides a similar application of systemic insecticides without waiting for the soil injected ' material to be moved through the roots (typically three months). The cost for a typical City street tree of 18 inches in diameter would be $42. This bid item was not in the original bid package. Scope of Services The street tree maintenance contract provides street tree maintenance services to the City. One three-person crew is hired for the full length of contract as needed for street tree maintenance services. A second crew will be scheduled for six months to concentrate only on block pruning. The contract also provides emergency services (if needed), tree planting, stump removal, and tree spraying services. The contract street tree maintenance services are essential to the City's on-going street tree maintenance program. Alternatives The alternative to extending the contract is to re-bid the contract. This will require at least 60 days to complete and involves considerable staff time. Staff does not believe a savings will be realized by a new bid. Staff pursued the multiple year tree maintenance contract lanauage provision to reduce staff workload, develop a long-term relationship with a viable tre~ maintenance contractor, and control costs. The current contract is accomplishing these goals. Fiscal Impact Funds have been requested for appropriation in the FY 2002-2003 Street Tree Maintenance Budget in the amount of $364,300. Tree maintenance contract expenditures were budgeted at $331,800. The remainder of the budgeted amount will be used for the contract Tree Preservation Ordinance permit inspection process which governs trees on private property, and the annual Elm Leaf Beetle control spray on Oakwood Boulevard. Staff will not initiate this contract until the City Council has formally approved the 2002- 2003 budget. Should the pending appropriation be deleted from the 2002-2003 budget, this contract will not be executed and the associated tree maintenance work will not be performed.
